Description
?
[technical field]
The present invention relates to the tunnel construction field, be specifically related to the dredger and the dredging method thereof in a kind of ring-like pre-buried bellows duct.
[background technology]
Known, to wear yellow tunnel and adopt the wholecircle Section Design, the internal diameter of tunnel is 7.0m; The external diameter of tunnel is 8.7m, and the lining cutting of tunnel is by inside and outside two-layer the composition, and is outer by 7 reinforced concrete prefabricated section of jurisdiction staggered joint erections; Wherein reinforced concrete prefabricated section of jurisdiction thickness is 40cm, and ring width is 1.6m, is to have to press to hold water owing to wear yellow tunnel; So for tunnel is satisfied the structural requirement that holds water is arranged, tunnel has increased inner lining structure again in tunnel after accomplishing the outer lining pipe sheet assembling; The inner lining structure that increases adopts posttension daraf(reciprocal of farad) prestressed concrete construction, and the liner of tunnel adopts the C40.W12.F200 prestressed concrete, and thickness is 45cm; The standard section length is 9.6m, and in the 9.6m scope, has laid 21 prestress anchorage cable ducts, and prestress anchorage cable duct spacing is 45cm; It is pre-buried that the duct adopts diameter to be that the bellows of 90mm carries out, and whole orifice throat length is 23m.
Because interior underboarding and limit crown will be divided into twice and construct, so bellows pre-buried also be pre-buried base plate earlier, it is pre-buried when constructing the limit crown, to carry out edge joint again in the practice of construction process; The pre-buried 6m lengthy bellows of base plate, 50cm is respectively exposed in both sides, and the limit crown adopts 3 bellowss to be connected to form complete reservation anchor cable pipeline; The crown position on the limit comprises that the horn mouth that connects bellows has formed 6 joints altogether, and joint adopts diameter 95mm; The overcoat bellows of long 50cm carries out socket; Bellows is reinforced with U shaped steel muscle and iron and steel wire after connecting moulding, and wraps up processing in the joint of sleeve pipe, is carrying out before inner lining concrete builds in the work progress; The workmen has taked multinomial measure to prevent that the bellows pipeline is blocked; But in the stretching construction process, bellows is dredged when inspection, still have the part bellows to be stopped up, make troubles to tensioning construction by concrete or concrete slurry.
Be the ring orientation prestress stretching construction owing to wearing yellow tunnel simultaneously, the prestressed pore passage hoop arranges that after bellows was blocked, the mediation difficulty was big, be difficult for mediation, and traditional dredging method was:
Method one: make the drill rod the same with the bellows radian, outside construction adds discontinuity knocks, and utilizes the impulsive force of drill rod to smash the tamper of chapelet face; Adopt this kind method to dredge, the progress of not only dredging is slow, and yielding after the drill rod commentaries on classics power when construction, and for the bellows of length 23m, behind the drill rod lengthening, more wayward, operation easier is very big; Drill rod mediation poor effect, drill rod mediation are that the point to the chapelet face cuts, and can not directly form a round diameter, are unfavorable for reeving, and have a strong impact on construction speed.
Method two: directly perforate is dredged choking portion on the inner lining concrete structure; Adopt this kind method favourable for handling very short stemming length, but long for stemming length, just can not handle with the method; Because perforate has a strong impact on xoncrete structure, so be unfavorable for later stage stretch-draw; And after perforate, carry out the backfill repairing and also have unfavorable factor, owing to be that New-old concrete is difficult to fully vibrate after the filling of crown position on the limit, bond between fresh and hardened concretes is insufficient, influences stretching construction.
Method three: cut the block part concrete, replace bellows again, again to cutting position casting concrete again; This method is applicable to that stopping up serious bellows handles; But cut the concrete destruction xoncrete structure, speed of application is slow, greatly destructive, and because tunnel bellows spacing is less; Cut the position just in time at stretch-draw local pressure position, there is unfavorable factor in the reinforcement concrete to the stretch-draw effect.
In sum; Adopt above-mentioned dredger and dredging method not only not to reach the effect of mediation, and depart from position, former duct easily, handle if blocking position is carried out perforate; Destroy former concrete structure again; Influence follow-up stretching construction, so how to provide a kind of promptly simple to operate on the basis of not destroying former concrete structure, device that mediation speed is fast again and dredging method have just become those skilled in the art's long-term technological demand.
